Pearson’s linear regressions of PV parameters with a value of PCC > 0.5 together Bland–Altman plots with limits of agreement < 50% and no significant biases. The consecutive graphs (6 a, b, c, d, e) represent the Pearson’s correlation and Bland–Altman analysis of the PV parameters for which our clinically acceptable moderate inter-technique agreement criteria were met. Bland–Altman plots of differences between 3DTOE and CCT, expressed as percentages of the values on the axis [(3DTOE – CCT) /average %)], vs. the mean of the two measurements. Areas between continuous lines present CI limits for agreement limits. Area between dashed lines presents CI limits for mean limits. The bias is not significant because the zero line is within the CI limits for mean limits. The 95% limits of agreement are presented as ± 1.96 SD. 3DTOE (Three-dimensional transesophageal echocardiography), CCT (Cardiac computed tomography), PV (Pulmonary vein), a (The major axis diameter of the PV ostium), b (The minor axis diameter of the PV ostium perpendicular to „a”), OA (Ostium area), LLR (Left lateral ridge), LSPV (Left superior PV), RSPV (Right superior PV), PCC (Pearson correlation coefficient), CI (Confidence interval), SD (Standard deviation)
